Triple That Handles Everything
The Trident 660 is Triumph's most approachable roadster, and it leans on the thing the brand does best: character. The 660cc inline-three makes 80 hp at 10,250 rpm and 47 lb-ft at 6,250 rpm, delivered in a smooth, rising rush rather than one flat plateau. Ride-by-Wire Throttle Maps, ride modes, traction control, and cornering ABS sit underneath, while a Showa SFF-BP fork holds up the front. Light on its feet at 419 lb and low at the seat, it slots into the class as the friendly, detail-rich option that still feels genuinely modern on the road.
This is a bike you ride every day without thinking twice. The chassis is easy, the controls are light, and the assembly quality holds up over years of miles, which is a big part of why it ages well. A deep aftermarket means you can shape it to your taste without spending a fortune. Be honest with yourself about the engine, though: 80 hp is plenty for real roads but modest if you crave big top-end. Watch the oil level, and know the front fork comes set from the factory with no adjustment to dial in.

The named systems that set this bike apart — and what each one does for you.
Connectivity
Thumb the starter and the triple settles into that offbeat, three-cylinder idle that gives the Trident half its personality. Roll on and the induction note hardens into a clean howl toward the top, with very little buzz reaching the bars or pegs. The riding position is upright and roomy, the reach to the wide bars gives you real leverage, and the low seat means you plant both feet flat at every light without stretching. At walking pace the 419 lb never feels heavy, and the bike tips side to side with a fingertip. The color display and connectivity sit right in your sightline, easy to read at a glance. On a flowing back road it stays planted and communicative, telling you what the front tire is doing without ever getting nervous.
What follows isn't my own test lap but the signal I've pulled together over years of listening to riders: notes swapped in the pits, long email threads, and the messages owners send me when something on their bike is worth flagging. On the Trident 660 that chatter lands in a consistent shape, a middleweight most people warm to fast, with two rough spots that show up once the road or the pace gets serious.
The strongest thread is how light and willing it feels, quick to steer and easy to trust through town and bends. Close behind, riders praise the triple for power that comes on smooth and progressive and pays you back for revving it out. Newer and returning owners keep calling it approachable, and plenty single out the value for what you get. The gripes are narrower. The one raised most is a snatchy throttle at small openings that turns abrupt in stop-and-go crawling. A smaller group flags a stiff front that jars over sharp bumps and wears on comfort as the miles stack up.
Excessive oil consumption
A subset of owners report unusually high oil consumption, with some bikes requiring frequent top-ups. In severe cases, this has led to engine rebuilds under warranty due to leaking camshaft seals. Triumph has attributed consumption up to 1 liter per 1000 miles as 'industry standard,' though many owners consider this unacceptable.
Map hose recall
A recall was issued for a map hose issue (specifics not detailed in available evidence). The recall addresses a potential fueling problem that could affect engine performance.
Throttle hesitation / stumble
Higher-mileage examples may develop a hesitation or stumble upon initial throttle opening, often attributed to fouled throttle bodies or sensor issues. This can make low-speed riding less smooth.
Warped rear brake disc
Some early units experienced a warped rear brake disc, often within the first few hundred miles. The issue was typically resolved under warranty by replacing the disc.
Where this Triumph Trident 660 pulls ahead of — or falls behind — its rivals on the numbers, and the typical bike in its class on character.

Forget spec-sheet bragging. Here's who the Trident 660 is actually built for.
You commute all week, then run Skyline and Alice's on the weekend. The Trident's light steering, low seat, and connected cockpit fit that life, and the triple sounds special enough to earn the photos.

You go to the Dragon and Cherohala to sharpen technique, not chase numbers. The Trident's easy handling and honest chassis feedback let you work on your lines corner after corner without the bike ever fighting you.

You know Angeles Crest cold and ride at a real clip. The Trident's light chassis and lean clearance reward smooth canyon pace, though its 80 hp will feel modest if you're chasing outright drive.

If this one isn't quite the fit, these are the bikes worth riding back-to-back against it.
Any price note compares both bikes at the same age — the youngest age both have on the used market — against this Triumph Trident 660. “cheaper/pricier” is what that bike costs second-hand, not how worn it is.
